ENTTED STATES PATENT @FFTQE PADLOCK.

Specification of Letters Patent.

Patented June 17, 1919.

Application filed. November 16, 1918. Serial No. 262,783.

Sill, county of Comanche, and State of Oklahoma, and I, JozErH LnsoINsKI, a citizen of the United States, residing at Fort Sill, county of Comanche, and State of Oklahoma, have invented certain new and useful. Improvements in Padlocks, of which the following is a specification.

This invention relates to improvements in looks and particularly those of portable type, commonly known as padlocks.

The principal object of the invention is to provide a novel form of lock and which is substantially unpickable.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in. the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a longitudinal sectional View showing the preferred form of lock construction, and, V

Fig. 2 is a transverse sectional view taken on line H of Fig. 1.

Referring to the drawings, the lock will be seen to consist substantially of a hollow cylinder 10 formed with rigid ends respectively 11 and 12, the latter being imperferate, while the circular end or head 11 has a central opening 14 for the insertion of the releasing element.

Encircling the end of the cylinder, adj cent to the wall or head 11, is a sleeve 16 having extending lugs 17 the same extend ing outward, parallel to each other and haw ing engaged therebetween, by the rivet 18, the bar 19 of a shackle 20, the inner edge of which is closely adjacent to the barrel 10. when the lock is in an engaged position it being understood that the bar is freely pivoted upon the rivet 1S.

Formed laterally in the barrel 10, near the head 12,. is an opening 22 in which is re- .ceived the inwardly extending end 21 of the bow, the same being provided with an opening 23, the rear edge wall of which is coincident with the interior wall of the cylinder 10 when the bow is in an engaged position.

A bolt 36 is slidable through an opening 1n the transverse wall 34-, and in an oppositely disposed opening is a slidable bar 10,

engaged with a disk 48, having a stem 39 screw threaded at its outer end and engageable with a suitable key or operating device, the disk being pressed normally inward by the efi'ect of the coiled compression spring ll. On the inner side of the bolt 36 are a plurality of rack teeth 42, while similarly the sliding bar 40 has rack teeth 43 upon its inner edge, engageable with which is a pinion l4 rotatably mounted upon a pin 4.5 set transversely in the cylindrical casing, adjacent to which is a similar pin 46 upon which is rotatably mounted another pinion 47, its teeth meshing with the teeth 42- upon one side and with a meshing pinion 44- upon the other side.

Thus as the screw key is entered, retracting the stem and disk 38, obviously the bar is drawn outwardly communicating rotatory motion through the pinion 4:4 to the pinion 47, which in turn draws the bolt 36 down wardly from the opening 23 permitting the lock to be opened.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is-

In a lock of the class described, the combination with a hollow cylinder having fixed walls at its ends, and shackle pivotally secured to the exterior of said cylinder, of a disk slidably engaged within said cylinder, a bolt slidably engaged internally of said cylinder having a part adapted to engage with the end of said shackle, a bar movable within said cylinder, said bar being attached to said disk, a pair of intermeshing pinions engageable within said cylinder, teeth on the adjacent sides of said bar and bolt, said teeth being engaged by said pinions respectively, resilient means for pressing said bar and bolt oppositely to lock said shackle when within said cylinder, and means for retracting said disk, and said locking bolt.

In testimony whereof we have affixed our signatures.
